Rooting/SD Card Problem

When I try to get root on my g1 I get to the "flash_image recovery recovery.img" step and I keep getting "error opening recovery.img: No such file or directory." I have tried changing recovery.img to /sdcard/recovery.img and I have made sure that I properly unmounted it from my computer. When I cd to sdcard and ls the only thing inside is dcim, but when I mount it to my pc again the recovery.img and update.zip folders are inside and nothing else.

Not sure what's up with your sdcard issue, but you could always just write the recov directly and bypass the sdcard:
On G1:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
On PC:
adb push /path/to/recovery.img /system/recovery.img
On G1:
cd system
flash_image recovery recovery.img

When I type "adb push /home/stephen/Desktop/recovery.img /system/recovery.img" I get bash: adb: command not found. Also, I am running Ubuntu 8.10 if that would make a difference.

In terminal, you have to cd into the directory where adb is found. It's probably easiest to put the recovery.img in the same directory as the adb file.
Try this:
adb remount
adb push recovery.img /system/recovery.img
that should work.

adb is a part of the Android sdk. If you haven't downloaded the sdk before, you'll need to do that.

Alright now I keep getting error: device not found even though I have mounted my g1.

You have to turn on debuging by going into settings->applications->development->debug

You need to follow the directions here:

Ok well I switched over to windows because Ubuntu was getting annoying and I installed sdk and everything and now when i enter "adb remount" I get remount failed: Operation not permitted. And if I put in "adb push recovery.img /system/recovery.img" I get failed to copy 'recovery.img' to '/system/recovery.img': Read-only file system.

Do you have rc29?

How to get APPS back into system/apps/

I updated my rom and there are some omitted apps that I would like to get back into system/apps/ for example VoiceDialer.apk, but I cannot seem to get them back on. I am using Fresh Rom 0.4 and the phone is obviously rooted. maybe I am doing something wrong in adb shell but I keep getting one of 2 different erors. Either permission denied or adb not found. Thank you in advance for your help.

1) Permission denied - make sure that when you do an adb shell, you're root (have the # prompt) and make sure you've mounted /system as rw (adb remount)
2) adb not found - make sure there's only one adb.exe on your computer and that it's the one from the SDK and that the SDK's /tools directory is in your path (to be safe, you can always just run adb from that directory)

1. the procedure I used is this: from the cmd prompt in the androidsdk/tools/ directory:
adb shell
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# cd /system/app
# adb push VoiceDialer.apk system/app
but its a no go. Can't understand why.
BTW, I have the VoiceDialer.apk file in the androidsdk/tools folder just to make the push easier.

Ok, here is a screen shot from my command prompt window. I know someone knows what the hell I'm doing wrong. Just wanna get the damn voice dialer back on my phone. Please help, thank you.

you cant do adb push while in shell ($ or #). Exit out and just try tying the adb push

When I do that I get permission denied or something to that effect.

Yeah there's a post about this in the Fresh thread.
The most straightforward way is this:
Reboot to the recovery partition.
adb shell into the phone.
Issue the following command to mount the system partition:
mount -t yaffs2 /dev/block/mtdblock3 /system
Type exit to exit the shell.
Then do:
adb push c:\directory-with-the-apks /system/app

[Solution]SAMSUNG GIO S5660: adb remount failed

Hi guys,
If any one getting error while remounting system partition in rw mode using adb, please follow these steps :
C:\Android\android-sdk-windows\tools> adb remount
remount failed: No such file or directory
SOLUTION:
Connect to your device usb adb: [FOR ROOTED DEVICES ONLY]
C:\Android\android-sdk-windows\tools> adb shell
$su
#mount -o remount,rw /dev/stl12 /system
(do your desired work like copy some files on system/media folder , then remount the system partition in ro mode again)
# cd /
#mount -o remount,ro /dev/stl12 /system
#exit
$exit
Thats all
FYI if you want to know the dev partitions mounted on your device :
C:\Android\android-sdk-windows\tools> adb shell
$ su
# mount
cheers

Did you map the other partitions by any chance? I'd like to be able to make a full backup to eventually be flashed back with Heimdall or ODIN. I already have a system.rfs (stock + root) that could be made in a tar image.
I've see tutorials for other Samsung phones but these need to be adapted to our exact setup. I haven't found anything generic enough to know how to go about mapping things.
It might also help those who flashed GT-S5660 ROMs on the Bell Canada GT-S5660M, as the screen brightness issues sound very much like kernel issues to me...
I can't quite tell what the difference is between stl and bml either. (I'll probably try dd'ing the different blocks, except stl5, and peek around with a hex editor...)
Goodbye,

rm failed for /system/app/nfc.app, Read-only file system

I am locked out of my Nexus S due to a Force Close loop with Nfc.app caused by installing a non-working fix for the Google Wallet app on the T-Mobile (thanks Google!). I therefore can't run root explorer etc.
I am trying to remove Nfc.app using but get these errors:
Code:
$ rm /system/app/nfc.app
rm failed for /system/app/nfc.app, Read-only file system
$ remount
remount: permission denied
# mount -w -o remount /system
Usage: mount [-r] [-w] [-o options] [-t type] device directory
Any way I can get past the read-only error, and the failure of remount?

Boot in recovery and run adb shell. That'll give you root permissions and access to the file system.
Greetz

That gives me:
error: device not found
I am using stock recovery (because it was a soft ClockworkMod recovery and I can't get back into ROM manager to reflash it).

Flash recovery with fastboot.

Thanks but I get:
$ fastboot flash recovery clockwork.img
fastboot: permission denied

Doing it wrong. Read the guides to learn how to set up and use fastboot.

I tried but that's all I came up with. If you could type the line of command I need, I'd really appreciate it, and give thanks

adb shell only inherently grants root permissions on an insecure boot image. If he's stock, rooted he'll get the standard user prompt and have to request elevated privileges.

No offense, but the Thanks Google is a bit snarky - they didn't provide for T-Mobile users and never distributed the APK to flash.
For something helpful though - go ahead and boot up normally. Grab a shell, su and remount /system manually
Code:
mount -o remount,rw /dev/mtdblock3 /system
You have to tell mount which partition to mount, it won't accept just a mount point.

Thanks, but how do I request elevated privileges? E.g. I get this:
$ mount -o remount,rw /dev/mtdblock3 /system
mount: Operation not permitted
And this:
$ fastboot OEM unlock
fastboot: permission denied
Seems I can't do anything from the $ prompt.
PS: My snark at Google was for releasing a fragmented product that was not available to T-Mobile in the first place, hence these problems with the cracked version.

Are you rooted - if so then su prior to issuing the mount command?
If not, Is the bootloader current unlocked? You don't use fastboot from the device shell. Fastboot is a command line utility used from your local computer to operate on the device when it is in the boot loader.

Bootloader was already unlocked.
I solved it:
Rebooted into fastboot mode by holding volume up and power
On computer navigated to folder containing fastboot and put the clockwork.img in there
Typed fastboot flash recovery clockwork.img
I now have CWM recovery back, thanks.

[Q] Can't mount the system after Root Nexus 5

Hi,all, I just get start with Nexus 5. can anybody tell me what the problem? follow with the command I input in windows shell.
K:\N5\ROOT>adb shell
[email protected]:/ $ su
su
[email protected]:/ # mount -o remount system /system
mount -o remount system /system
mount: Permission denied
255|[email protected]:/ #

Anyone on this?
Cheers!

su
mount -o remount,rw /system
However this only works if you have a custom "insecure" kernel that allows adb to do root things.

Thanks for the reply!
So, I will write my story here, hopefully to help some other guy in the future!
Basically I was on debug build from AOSP for the N5! And I installed all proprietary files from Google, LG, Qualcomm etc! But camera was faulty! So I decided to flash the stock images from Google! Then I 've lost
Code:
adb root
So I flashed the boot image from the debug build I had previously!
adb root works like charm!
to flash it, I used: fastboot flash boot boot.img
